its usally low pig tails for me, if you wear them to high your helmet pushes on them and its uncomfortable and can be painful. But unrestrained is not an option… I agree with rowan
If I don't do anything with my hair, just leave it down, it gets really wild by the end of the day.
I usually have long hair and it is CRAZY when I dont restrain it… I have it pretty short right now and the low ponies work well for that length too.
